Which epuation could be used to represent the table shown?

n: 10,12,15,19
m: 0,2,5,9

a) m=n/10
b) m=10-n
c) m=n+10
d) m=n-10

me on this on

D

Step-by-step explanation:

We observe that the values of m are 10 less than the corresponding values of n, that is

n = 10 → m = 10 - 10 = 0

n = 12 → m = 12 - 10 = 2

n = 15 → m = 15 - 10 = 5

n = 19 → m = 19 - 10 = 9

In general

m = n - 10 → D

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
